They revised the recipe for Pierogi

Early 20th century strife would be my guess.

A primarily contraction driven flexion of the elbow can never approach the precision of a multi joint move of which a collapse of the elbow joint is a component.

You will be able to collapse the elbow joint and be accurate, sure. But to do so with touch and precice force control, you will need more than merely firing an elbow flexor.

Also, contractions fall pray to nervous tension. Repeatable forces don't. If you want access to those, multi joint movement is the way. The symphony beats a solo act every time.

I've had some piano lessons and drum lessons and this whole idea of "correctly" pushing a stick along its length is kinda silly. To be fair, so is "correct" drum technique but that's another flame war.

Ingrained shit like how you regularly eat - pfft, if you can regularly eat, all affect how a pool stroke will act.

So there, push it along its length, is the idea. Have fun.

As I said, you can take a full course or two on this and not fully get it. Movement is very complex. This is why it is relatively easy to program a computer to think like a human, but we are a long way off from programming a robot to move like a human.

The point isn't that the elbow moves. It's that multi joint movement is an immaculately coordinated blending of repeatable forces and contractions. This is how it works in all vertabrates and has done so for millions of years. Overriding that and instructing the body to fire this muscle and then that one will never be able to compete with how your body would figure out how to efficiently make a desired action.

The prefrontal cortex has veto power so if you say to yourself 'only use elbow flexors' your arm will listen to you. If you instead intend to move the tip of the cue at some desired speed without a care for how, the body (your subconscious) will use all the tools at it's desposal to make that happen. Without a shadow of a doubt, it will do a better job than you bossing the arm around.

So as I said, "stroking should be left to the subconscious" is currently the best advice we've got.

Pocket size should be a spec.

Ok, I’ll try to clean these pads Thanks

("Multi-joint" strokes) are more in line with how we are designed to move and how we are wired to organize movement. They provide effortless power and a level of fine force control (speed control) that cannot be matched by primarily contraction driven movement. Not to mention the fact that they hold up incredibly well under pressure. They are in a word, better.

FYI, there at 10 money spots available, and only 4 people have participated to date. It would be sad if money goes unclaimed. For the current standings and for info on how to participate, see: $3,000 Billiard University (BU) Draw/Follow Challenge.

FYI, there is an advantage to locking in scores early since a tie goes to the first person who posted.
